PAPER-FEED FOR PERFORATING-MACHINES- Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed May 24. 1906. Serial No. 318,521

Be it known that I, PmLiP J ACOB MEAHL, a citizen of the United States,and a resident of Bayonne, county of Hudson, and State of New Jersey,have invented certain new and useful Improvements in Paper-Feeds forPerforating-Machines, of which the following is a specification.

My invention relates to means for feeding forward paper in aperforating-machine.

It is especially adapted to machines for perforating music-sheets, suchas are used in pianolas, pianolapianos, and similar mechanical musicalinstruments or players. For economy of production it is advantageousthata large number of these sheets, say fifteen or more, should beperforated at once and that the machine should be operated at-a highspeed, say seven hundred and fifty revolutions per minute. As the sheetsof paper are of considerable length, up to ninety feet, it is veryimportant that they shall be fed forward very accurately step by stepand that all the sheets shall be fed forward together without anycreeping of any of the sheets.

The object of the present invention is to provide means for theseresults, as well as toprovide means for stopping the machine verypromptly at will whenever this becomes necessary.

Further objects of the invention will appear in the specification and bepointed out in the claims' In the drawings, Figure 1 is a side elevationof so much of a paper-feed as is necessary t show my invention. Figs. 2,3, and 4 are vertical transverse sections .through the planes 2 2, 3 3,and 4 4 of Fig. 1, respectivelyl -1 designates the frame of the machine,which is suitt f supported by means not shower, and consists of twosuperposed parts 2 and 3. These can be separated from each other toallow for variations in the thickness at paper or the number of sheets.As a means to. this end I have shown dowel-pins 4 4, passing intoregistering apertures in the frames 2.21m 3, the frames being separatedby a strip of metal or the like 5, the thickness of which may be variedas desired. It is obvious that other means for adjusting the distancebetween the frame parts 2'and 3 may be substituted. Mounted on the upperframe part 1 and passing-transversely thereacross is a shaft 6, carryinga gear-wheel 7 at one end, and sprocket-wheels 8 9, which are spacedapart from each other to a distance s ightly greater than the width ofthe paper sheets to be fed. In a suitable aperture 10 in the frame part2is adjustably mounted a pair of journals 11, in which rotates a shaft12. An adjusting-screw 13 is provided for securing the proper tension ofs rocketchains 14, which engage in the test of the sprocket-wheels 8 and9, mounted on the shaft 6, and in the teeth of sprocket-wheels 15,mounted on the shaft 12. chains consist of the usual links 16, connectedby pins 17, on which are mounted rollers 18. Passing between the twosprocket-chains 14 at frequent intervals are cross-bars 19, faced withrubber or similar strips 20. Secured to the frame portions 2 areinwardly-projecting brackets 21 through which freel pass headed pins 22,the lower ends of which are secured at opposite ends to a cross-bar 23,springs 24 being placed on the pins 22 to force the bar 23'downward. Ateach end of the bar 23 and beneath the same are secured presserbars 25,which bear u on the rollers 18, between the links 16 of tl fesprocket-chain. Mounted on the lower frame part 3 are parts preciselysimilar to those described and numbered from 6%025 inclusive, thegearwheel 7 on the lower shaft 6 being in mesh with the gear-wheel 6 ofthe u per shaft 7. The effect of this is that when the shaft 6 isrotated the sprocket-chains 14 and 14 will be caused to travel withtheir adjacent faces in the same direction, so that the rubber strips onboth the upper and lower sides of cross-bars 19 will be ressed towardeach other. Between the rubber faces 20 of the upper and lowersprocket-ohains is passed a plurality of sheets of paper 26. i

a means of feeding forward the sprocket-chains 14 and 14, and therebyfeeding the paper sheets 26 in the desired direction, I provide a trainof gears consisting of a pinion 27, meshing with the teeth of thegearwheel 7. Mounted on the shaft with this pinion 27 is a Geneva .wheel28, shown as aving eight teeth which en age .vith a in 29, mounted on apinion 30, tile pinion eing provided with a crescent-shaped plate 31,bearing a ainst the concave faces of the Geneva w eel 28 to preventslipping of the same. As shown, the teeth of the mion 30 mesh with teethmounted on a beve gear 32, which meshes with a corres ending bevelgear33 ,on a shaft 34, to wfiichcontinuous The sprocketlIO motion isimparted by means not shown, but which may be connected with theperforating portion of the machine, the Geneva wheel .28

and the pinion 27, secured thereto, both being 5 mounted on a hub 35 forsliding motion on a the pin 40 is engaged in the inner an ular;

' groove 37 the Geneva wheel 28 will mesh with the pin 291a11d thepinion 27 will mesh 5 with the gear-wheel 7-, and that when the Y eratorslides the wheel 28 outwardly on t e shaft 36, so that the finger 40engages with the outer annular groove 38, the; Geneva wheel 28, and thepinion 27 will be: d,rawn 2,0 from their respective engagements andthe,movement of the paper-feeding. chain's stopped;

viousfrom the foregoing description- 1t- 2 5 will be seen that thepresser-bars 25, runnin I on the rollers 18 of the sprocket-chains, .wilproduce very little friction and will act efficiently to hold the rubberfaces 20"of the bars 19 closely against the upper and under sides of thepaper sheets, the pressure being equal from side to side, and therebysecuring the even feed of all the sheets It will also be seen thatby'providing the adjustable journals 11 at the same ends of all thesprocket-chains the adjustment of the chains to compensate for wear, ismade possible without in any Way interfering with the registrationof thecross-bars-19 on the opposite pairs of chains. It will also beunderstood 0 that mechanical modifications may be made in the devicewithout departingfrom the in- 'vention.
